I think Curry's game is more suited to dominating a regular season than dominating the playoffs and finals. Still they won and title and nearly another because they have such a talented team with so many weapons.
The individual players who typically dominate the playoffs are physical beasts or they BECOME physical beasts as a way to get though this thing. Jordan and Kobe scored a ton as thin athletic high flyers out of the gate in the playoffs but they became consistent winners in the playoffs when they bulked up. Then you've got guys like Shaq and LeBron who are physical mismatches from day one, Magic was a beast compared to the guards he could line up against.
Curry could heat up and carry a team to a title, he could have crazy scoring averages in the regular season, but I don't ever see his playoff scoring INCREASING over his regular season scoring the way shooting guards like MJ, Kobe and Wade could.
I think two things happened to Curry:
1) I think his injury spooked him a little bit and made him avoid contact. His 3 point shooting is obviously impressive, but in the regular season he was just as impressive getting to the rim and finishing. He'd often get his stroke going getting to the line. He just really had no interest going into the paint this series.2)
2) I just hated the way the whole series was officiated. He couldn't get any space because he was getting abused trying to get through screens. There was one point last night where Thompson was literally hugging him off the ball. In a way I like letting them play, but that was no the way the league was officiated all year up to the finals.
